Contact me on Discord if you have any comments, questions, or concerns, which might not belong in a GitHub issues ticket. My Discord handle is samuelvenable. This project is based on ImFileDialog by dfranx, with many bugs/crashes fixed and overall improvements. There are two backends to select from--SDL2 Renderer and OpenGL, (use SDL2 Renderer for Metal, since Apple deprecated OpenGL). SDL2 Renderer is used by default; enable using OpenGL instead by defining the IFD_USE_OPENGL macro. The 'Quick Access' sidebar actually remembers what favorites were previously saved to it from previous runs of your application now, by saving the settings to a text file in a hidden configuration subfolder of your home folder. Allows for full localization among many other good things you'll find useful. Most of the dialog is customizable via environment variables. To create your own default list of favorites for your application, here is a minimal example:
/*
** Alternative main.cpp - replace libfiledialogs/filedialogs/main.cpp with this exact code
** then if on Windows open the solution in Visual Studio and build with that otherwise run
** the build.sh script if you are building with g++ or clang++, depending on the target OS
